How to set DateTime range on X axis for System.Windows.Forms.DataVisualization.Charting?

You can set a DateTime range on the X-axis for the System.Windows.Forms.DataVisualization.Charting.Chart control by using the ChartArea.AxisX.Minimum and ChartArea.AxisX.Maximum properties. Here's an example:

// Create a new chart control Chart chart = new Chart(); // Add a new chart area ChartArea chartArea = new ChartArea("myChartArea"); chart.ChartAreas.Add(chartArea); // Set the X-axis minimum and maximum values to a date range DateTime minValue = new DateTime(2021, 1, 1); DateTime maxValue = new DateTime(2021, 12, 31); chartArea.AxisX.Minimum = minValue.ToOADate(); chartArea.AxisX.Maximum = maxValue.ToOADate(); // Add some sample data to the chart Series series = new Series("mySeries"); series.ChartType = SeriesChartType.Line; series.Points.AddXY(new DateTime(2021, 1, 1), 10); series.Points.AddXY(new DateTime(2021, 2, 1), 20); series.Points.AddXY(new DateTime(2021, 3, 1), 30); chart.Series.Add(series); // Show the chart on a form Form form = new Form(); form.Controls.Add(chart); form.ShowDialog();

In this example, we create a new Chart control and add a new ChartArea to it. We then set the Minimum and Maximum properties of the X-axis of the chart area to a date range by converting the DateTime objects to a double value using the ToOADate() method.

We then add some sample data to the chart by creating a new Series object, setting its ChartType property to SeriesChartType.Line, and adding some points to it with DateTime values. Finally, we show the chart on a form by adding the chart control to the form and calling ShowDialog() on the form.

Note that the Minimum and Maximum properties of the X-axis should be set to double values, so we need to convert the DateTime values to a double value using the ToOADate() method. This method returns the number of days between the date and time represented by the DateTime object and midnight, January 1, 1900, as a double value.
